After lots of research I ended up using this one, with the correct clamp shape for the blades of my fork.
It does flex quite a bit, and doesn't serve as a true front brake. At best it's a brake for trailing, not sure how it would hold up if one were to grab a fistful of brake in an emergency.
The insert-style caliper mount does look super clean, but I have the same reservations as others about fitment/clearance.
